BDR management is primarily accomplished via SQL-callable functions.
Functions intended for direct use by the end user are documented here.

All functions in BDR are exposed in the bdr schema. Unless you
put this on your search_path you'll need to schema-qualify their
names.

Warning

Do not directly call functions with the prefix
internal, they are intended for BDR's internal
use only and may lack sanity checks present in the public-facing
functions and could break your replication setup.
Stick to using the functions documented here, others
are subject to change without notice.
